4.7 / 5.049 ReviewsGood InvestmentUse this consistently now for getting my fermentation off on a quick start. Quality seems good, no issues with foam stopper. Flask is easy clean up and handles boiling wort transfer to ice bath fine. As mentioned in other reviews, evaporation is not accounted for (shooting for 1.040 OG), I've never measured but have had no problems thus far.December 31, 2012Best way to keep your yeast happyI recently got this kit for christmas. I made my first starter today for a winter braggot. The flask is a nice size and is lab-quality. This came with enough DME for about 3-4 starters. highly recommended.January 5, 2013Cheap FlaskYeast starters are important but this flask is junk. My particular flask in my kit was from India. I don't know if flasks in this kit changes but this one from United is just plain crap. The glass barely touched the side of a pan and the bottom section just popped off. I knew from handling the flask it was thin but I had no idea. Gone after not even one use and with it my DME. Stick with Pyrex or qt jar. This flask is so thin it almost feels like plastic. I am surprised that Midwest even sells this flask._x000D_Tried to give it zero stars but I guess that is not an option.August 29, 2015A good starter kitYou want the 2 liter beaker , not the 1 liter, in case you want to make a starter for a lager, or a big beer, or have older yeast. The other thing you need (really need) is a stir plate.January 3, 2013A Must HaveThe 2L erlenmeyer flask is of nice quality and should be able to withstand direct heat followed by a cold water bath, but I am not a gambler, so I start with a hot water and slowly bring the temperature down._x000D__x000D_You most certainly could use a rubber stopper with airlock, but the foam stopper allows oxygen into the flask, which is necessary for a successful/quality yeast starter. The foam will still keep the bad stuff out.. You can also keep the foam in while you boil the starter on your gas burner, so no need to mix up any sanitizer.January 6, 2013complete starter kitWent for the 2L kit for the bigger flask and the nutrient. Also ordered a stopper and another airlock. The instructions could use some updating. They never mention the foam stopper. On the advice of a friend I used it to allow oxygen in. I soaked it in some sanitizer and wrung it out. Yeast seemed happy.February 8, 2013Almost thereJust get a stir plate and stir bar and you are all set. The advantage of the 2 liter flask is you can make a bigger starter, and don't have to worry about boil over as much. The foam stopper is all you need, you don't want an airlock for starter, you want the gasses to flow freely.February 9, 2013Better fermentationI bought this kit to improve my fermentation, to avoid it stalling out before finishing. I think it's helped because since using it I have had complete fermentations.February 22, 2013Great kit!Everything arrived package well and in good shape. I made my first starter this week. The DME & nutrients performed as advertised and I had super fermentation within hours. The flask is thicker than I had expected seems plenty sturdy.March 1, 2013Took my fermentation to a new levelI've used this set-up now for about the past 4 brews & it has made a noticeable impact on the lag time & intensity of my fermentations. I also purchased a stir plate which is well worth the money. _x000D__x000D_Have been using a little over 1 Liter of water combined with a cup of DME to create my base wort. _x000D__x000D_No challenges taking boiling wort into the flask & dunking straight into an ice bath. The high grade flask will withstand the extreme temperature fluctuations. I usually let my starter sit on the stir plate for 36 hrs, then cold crash for a few day before decanting off the starter wort. _x000D__x000D_Do not use a airlock when making a yeast starter...the foam stopper that comes with the kit is perfect. You want to let oxygen into the wort when building a starter. (Not to be confused with the absolute necessity of keeping O2 out of your main wort once the primary phase of fermentation is complete).March 4, 2013
